Reclaimed Asphalt Pavement Regeneration Technologies

Technology Overview

Reclaimed Asphalt Pavement Regeneration Technologies.
Reclaimed Asphalt Pavement Regeneration Technologies.

The Reinforced Asphalt Rejuvenating Agent (ARA) and the Reclaimed Asphalt Pavement (RAP) Regeneration Technologies can be used to solve the problems relating to the stacking and reuse of RAP. The recycled asphalt concrete will then comply with the global high quality Hamburg Wheel Tracking (HWT) Test standard, while the RAP can be fully recycled and reused. The goal of becoming an exemplar of the circular economy can then be achieved since waste is turned into resources. The strengths of these technologies include high performance, high quality, and high circulation.

Applications & Benefits

Through these technologies, the amount of ARA used will be reduced by more than 60%, and the recycled asphalt concrete can be used with basic oxygen furnace (BOF) slag materials to reduce resource (sandstone and asphalt) consumption. A facility for the pilot production of ARA has been established (with an annual production capacity of 1,000 tons), and ARA with an area of 340 hectares has been applied to roads. If exclusively RAP is subsequently used on road surfaces, the consumption of sandstone and asphalt will be reduced respectively by 4.3 million tons and 180,000 tons every year.
